Journal of Aquatic Plant Management, 37a:67-71. The influence of hydrilla leaf quality on larval growth and development of the biological control agent Hydrellia pakistanae (Diptera: Ephydridae). Plectosporium tabacinum, a pathogen of the invasive aquatic weed Hydrilla verticillata in Florida. 17th ICID International Congress on Irrigation and Drainage, Granada, Spain, 13-17 September 1999. Epiphytic cyanobacteria found on hydrilla are thought to be the agents producing a toxin that causes avian vacuolar myelinopathy (AVM) a disease that has killed at least 100 bald eagles (Haliaeetus leucocephalus) and thousands of American coots (Fulica americana) since 1994 in locations from Texas to North Carolina, USA (Wilde et al., 2005). H. verticillata forms dense masses, which may completely fill the volume of waterbodies. 2. Novelo A, Martínez M, 1989.
